片段添加此代碼不甲肝e onActivityResult,因此您可以在其中創建或附加片段,並在其中添加onActivityResult和其他句柄。 – CrazyMind

試試這個,對我的工作

在主要活動

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     try { 
       for (Fragment fragment : getSupportFragmentManager().getFragments()) { 
       fragment.onActivityResult(requestCode, resultCode, data); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    }
